| Abstract: | This paper proposes an off|line parametric design method based on 3D solid model from a 3D reconstruction system. In this system, 3D solid models and 2D projective graphic entities are coexistence. Via building the relation between primitive and its 2D projective graphic entities and the relation between dimension and 2D projective graphic entities and the relation between primitive and primitive, this paper builds the parametric model based on 3D reconstruction and realizes the off|line parametric design in which dimension can drive the corresponding graphic. |
